Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies We are the subject of lawsuits and claims arising in the ordinary course of business from time to time. A liability is accrued when a loss is both probable and can be reasonably estimated. We had no material accruals for loss contingencies, individually or in the aggregate, as of September 30, 2017 and December 31, 2016. We believe the probability is remote that the ultimate outcome of these matters would have a material adverse effect on our financial position, results of operations or cash flows. We are conducting an internal investigation of the operations of certain of our foreign subsidiaries in West Africa including possible violations of the U.S. Foreign Corrupt Practices Act, our policies and other applicable laws. In June 2016, we voluntarily disclosed the existence of our extensive internal review to the SEC, the United States Department of Justice and other governmental entities. It is our intent to fully cooperate with these agencies and any other applicable authorities in connection with any further investigation that may be conducted in connection with this matter. While our review has not indicated that there has been any material impact on our previously filed financial statements, we have continued to collect information and cooperate with the authorities, but at this time are unable to predict the ultimate resolution of these matters with these agencies. In addition, during the course of the investigation, we discovered historical business transactions (and bids to enter into business transactions) in certain countries that may have been subject to U.S. and other international sanctions. We have disclosed this information to various governmental entities (including those involved in our ongoing investigation), but at this time are unable to predict the ultimate resolution of these matters with these agencies, including any financial impact to us.
